Granted that is not true all the time, but probably 95% of the time. So, I bite my tongue when someone is venting and I want to say something.
Tonight, I broke that rule and shouldn't have. My guy's brother is a piece of work, and teats his gf (mom to his kids) like dirt though she has stood by him for years. Nothing I say will make her change it. But I spoke up anyway. It WILL bite me in the ass, as she will probably tell him what I said.
So, what is your policy? Do you bite your tongue, or tell them like it is?
